2DduplexingPCA(2D2PCA)

Matlab, Simulink Building a direct sequence spread spectrum model

this is matlab code for fourier transform and window function comparision

matlab编写的边缘检测程序，可以准确识别出图像的边缘。(edge detect)

I am doing research in wireless sensor network in data aggregation. here cluster head send packet to base station .by using k means cluster algorthim A network is divided into k layer. k cluster are formed in k layer . each cluster has one cluster head . all cluster member send data to its corresponding cluster head by using TDMA . the cluster head performs the data aggregation and forward packet to base station .

用于电力电子系统同步信号检测或故障分析的对称分量法正负序分离(Symmetrical components for the power electronics system synchronization signal detection or failure analysis of positive and negative sequence separation)

应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 (DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.)
